CryptoLite Virus – Distribution Ways
The CryptoLite virus is currently being distributed in a test campaign. It is presumed that in the future the hacker or criminal group behind it will utilize several tactics to increase the number of infected hosts.
One of the main methods that can be used is the creation of email phishing campaigns that use the design elements of legitimate web services and sites in order to confuse the victims into interacting with them. The viruses are either directly attached or linked inthe body contents of the message.
The other method relies on the use of fake download sites that pose as legitimate vendor download sites, portals and other services that are frequently accessed by computer users. These two mechanisms are the primary ways to distributed payload carriers, two are the most popular types:
Documents — The hackers behind the CryptoLine virus can embed macros scripts in various files (rich text documents, spreadsheets, presentations and databases). When they are opened a notification prompt will appear asking the users to enable the built-in scripts. This leads to the virus infection sequence execution.
Application Installers — The same technique can be applied to software installers of popular applications. They are made by taking the legitimate installers from the official sites and modifying them to include the CryptoLite virus code.
To further increase the number of infected hosts the criminals may also utilize browser hijackers — they represent malicious plugins that are made available for all popular web browsers. They are usually distributed on the associated browser repositories and make use of fake developer credentials and user reviews to advertise them. Their typical behavior is to redirect the victims to a hacker-controlled site, the additional scripts lead to the virus infection.
CryptoLite Virus – In-Depth Analysis
It appears that the CryptoLite virus is not based on code taken from any of the famous ransomware families. It appears that the hacker or criminal collective behind it have either made it from scratch or have acquired a code that has not yet been identified by the current anti-virus and anti-spyware signatures as belonging to one of the already known families.
The captured samples are currently being analyzed and the available reports so far indicate that they are test releases. It is ery possible that the limited distribution campaign is merely used to plot out future attacks that would carry updated samples. The main malicious engine has been found to use a modular approach, this allows the criminals to customize the attacks depending the targets.
The infections can begin with a data harvesting module programmed to harvest sensitive strings. They can be classified into two main groups:
Private User Information — The engine can be configured to seaerch for strings that can directly expose the identity of the users: their name, address, phone number, location, interests and account credentials.
Anonymous Metrics — The other type of information that can be harvested by the engine is used to optimize the attacks. It collects information such as the user-set regional options, a report of all hardware devices and certain operating system values.
This data can be processed by the next component in the sequence which can bypass security software. The list includes anti-virus programs, sandbox (debug) environments and virtual machine hosts. Their real-time engines can be bypassed or completely removed, depending on the instructions by the hackers.
After this has been complete the engine can proceed further with system changes. They can be different according to the defined sequence, however in most cases some kind of a Windows Registry modifications is made. They can be against the user-installed applications or the operating system entries themselves. Such changes can result in the inability to start certain functions and the overall performance may degrade.
The CryptoLite virus can be installed as a persistent threat — it will automatically start once the computer boots. Such behavior also interacts with the boot recovery menu by disabling it. This makes it very difficult to employ most manual removal methods.
In certain cases a separate Trojan instance can be set which connects to a hacker-controlled server. This allows the criminals to spy on the victims, overtake control of their machines and deploy additional threats.
CryptoLite Virus — Encryption
Following the succesful execution of all prior components the ransomware engine will be launched. It uses a built-in list of target file data that is encrypted with a strong cipher. An example list includes the following files:
Images
Archives
Documents
Backups
Databases
Music
Videos
Instead of a ransomware note it uses a lockscreen instance which prohibits ordinary interaction until the threat is completely removed. It reads the following message:
ALL YOUR FILES HAVE BEEN ENCRYPTED!!! There’s no way to decrypt these files without the decryption key. To retrieve the deceryption key a payment of 0.5 BC will need to be paid. INSTRUCTIONS: *Purchase the bitcoins from https://localbitcoins.com/. *Transfer the bitcoins to a https://blockchain.info/ Wallet. *From https://blockchain.info/ transfer the bitcoins to the below address. *Add a message to the transaction with the following format: {MAC-ADDRESS_EMAIL} <- ENSURE THIS IS CORRECT
Example:
00:A0:C9:14:C8:[email protected]
Following payment the key will be emailed to you after confirmation.

4. Try to Restore files encrypted by CryptoLite
Try to Restore Files Encrypted by CryptoLite
Ransomware infections and CryptoLite aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested several alternative methods that may help you go around direct decryption and try to restore your files. Bear in mind that these methods may not be 100% effective but may also help you a little or a lot in different situations.
Method 1: Scanning your drive’s sectors by using Data Recovery software. Another method for restoring your files is by trying to bring back your files via data recovery software. Here are some suggestions for preferred data recovery software solutions:
Method 2: Trying Kaspersky and EmsiSoft’s decryptors. If the first method does not work, we suggest trying to use decryptors for other ransomware viruses, in case your virus is a variant of them. The two primary developers of decryptors are Kaspersky and EmsiSoft, links to which we have provided below:
To restore your data in case you have backup set up, it is important to check for Volume Shadow Copies, if ransomware has not deleted them, in Windows using the below software:
Method 4: Finding the decryption key while the cryptovirus sends it over a network via a sniffing tool.
Another way to decrypt the files is by using a Network Sniffer to get the encryption key, while files are encrypted on your system. A Network Sniffer is a program and/or device monitoring data traveling over a network, such as its internet traffic and internet packets. If you have a sniffer set before the attack happened you might get information about the decryption key. See how-to instructions below:
